Front

What is the definition of Simple Probability?

Back

Simple Probability is the measure of the likelihood that a specific event will occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

What does the symbol ( ∩ ) represent in set theory?

Back

The symbol ( ∩ ) represents the Intersection of two sets, which includes all elements that are common to both sets.

Front

What is the definition of Union in set theory?

Back

Union is the operation that combines all unique elements from two or more sets, represented by the symbol ( ∪ ).

If A = {1, 2, 3} and B = {2, 3, 4}, what is A ∪ B?

Back

A ∪ B = {1, 2, 3, 4}

Front

What is the formula for calculating the probability of an event?

Back

The probability of an event P(E) is calculated using the formula: P(E) = Number of favorable outcomes / Total number of outcomes.
